Patent EP-0250985-A2 (EP)
Inventor: TOWLSON HOWARD EARLE
IPC: H01J29/89
Filed: 1987-06-12
Abstract: A flushing system is provided for a light valve of the Schlieren dark field type. A small amount of filtered fluid is injected into the space between the rotating disc and the output window of the light valve. This is done by injecting the fluid through the center disc bearing, thereby providing a uniform radial flow outwardly from the center and flushing out any particles in the space and preventing any particles in the surrounding fluid from moving into the raster area. By properly regulating the flow of the center flush fluid, the disc can be floated off the support during rotation. This reduces wear generated particles which contribute to substrate buildup and subsequent loss of light throughput. In addition, erratic disc motion caused by a stick and slip frictional effect is reduced.

Abstract: The wheel has a rigid rim, which has clinches extending essentially radially inwards, and a pneumatic tyre, which is attached by its heels on the radially inner side of the rim next to the clinches, and at least one single-piece covering ring, which fills the space axially towards the inside from the tyre heel and has several circumferential hollow chambers, one of which, facing the adjacent tyre heel serves for receiving a balancing weight and, for this purpose, the outside of the covering ring, facing the tyre heel, has a slotted opening at least in the region of the balancing weight. In order to ensure that the slotted opening remains closed in all operating situations, it is proposed that catch means are situated radially towards the inside from the slotted opening on the covering ring and/or on the tyre heel, which catch means prevent unintentional detachment of the covering ring with the balancing weight. In particular, a circumferential rib on the covering ring and a circumferential groove on the tyre heel to receive said rib can be used as catch means. <IMAGE>

Abstract: A variable capacity vane compressor has a cylinder within which a pair of compression spaces are defined between the cylinder and a rotor rotatably received within the cylinder at diametrically opposite locations, and a control element (24) disposed in the cylinder for rotation about its own axis in circumferentially opposite directions in response to a difference between pressure from a lower pressure zone and pressure from a higher pressure zone. The control element has its outer peripheral edge formed with a pair of cut-out portions (25₁,25₂) at substantially diametrically opposite locations, which each have a leading end (25₁₀,25₂₀) in the direction of rotation of the rotor. The rotation of the control element causes a change in the circumferential position of each cut-out portion to thereby vary the timing of commencement of compression in the corresponding compression space and hence vary the compressor capacity. The leading ends (25₁₀,25₂₀) of the cut-out portions are located at diametrically asymmetric locations to provide a difference in the timing of commencement of compression between the compression spaces. Therefore, the compressor as a whole is free from insufficient compression and can provide sufficient discharge pressure even when it assumes the minimum capacity position.
